“…The salinity and DO ranges also clearly differed between O. javanicus-only and O. dancena-only sites: O. javanicus inhabits environments with higher salinity and higher DO. The border between the species' habitats is around 1/3 that of seawater, which corresponds to the body fluid osmolality of teleosts (Takei et al 2011 (Inoue and Takei 2002). Kang et al (2008) also demonstrated that the amount and activity of Na + /K + −ATPase in O. dancena in fresh water is higher than in fish acclimated to 15 ppt salt water, suggesting that this species consumes more energy to adapt to fresh water than to a hyperosmotic environment.…”

Among ricefishes of the genus Oryzias, the Javanese medaka (O. javanicus) and the Indian medaka (O. dancena) are highly adaptable to seawater. Although wide distribution of the two species in the brackish waters of South and South-East Asia has been reported, their habitat preference remains unknown. We surveyed 12 sites in five estuarial areas of the west coast of Peninsular Malaysia from Kuala Gula to Tanjung Piai. Both species were found in all five areas, suggesting their distribution throughout the west coast of Peninsular Malaysia. This is the southernmostrecorded appearance of O. dancena, to the best of our knowledge. However, the habitats of the two species were essentially separated: of the 12 surveyed sites, the species were found in co-existence at only two sites, and one or the other species was found alone at the remaining 10 sites. We compared temperature, salinity, pH, and dissolved oxygen (DO) at the sampling sites and found that the habitat of O. javanicus is with higher salinity and DO. The salinity and DO at the sites of co-existence are near the lowest values found at the O. javanicus-only sites, and the highest values at the O. dancena-only sites. These results suggest that O. javanicus and O. dancena habitats are essentially separated; the former prefers hyperosmotic conditions while the latter prefers hypoosmotic conditions, and the latter may be more tolerant of hypoxia. The two sites of co-existence are points of contact between the species' separate distribution areas.

“…Considered to have a long lineage dating back to jawless fish (Takei et al 2011), CNP is expressed in all mammals studied to date and in a wide range of tissues (Minamino et al 1993) where the hormone, acting locally via its specific receptor (natriuretic peptide receptor B; NPRB), is thought to regulate cellular proliferation and maturation (Potter et al 2006). Convincing evidence from the last decade shows that CNP is essential for postnatal skeletal growth (Chusho et al 2001).…”

Studies from genetic modification and spontaneous mutations show that C-type natriuretic peptide (CNP) signalling plays an essential part in postnatal endochondral growth, but measurement of CNP proteins and changes in their abundance in tissues and plasma during normal growth has not been reported. Using rodent pups with GH deficiency, we now describe the pharmacodynamic response of CNP and rat amino-terminal proCNP (NTproCNP) in plasma and tissues, and relate these to changes in linear growth (nose-tail length, tibial length and tibial growth plate width) during the course of 1 week of GH or saline (control) administration. Compared with saline, significant increases in plasma and tissue CNP forms were observed after 24 h in GH-treated pups and before any detectable change in linear growth. Whereas CNP abundance was increased in most tissues (muscle, heart and liver) by GH, enrichment was the greatest in extracts from growth plates and kidney. Plasma and tissue concentrations in GH-treated pups were sustained or further increased at 1 week when strong positive associations were found between plasma NTproCNP and linear growth or tissue concentrations. High content of NTproCNP in kidney tissue strongly correlated with plasma concentrations, which is consistent with previous data showing renal extraction of the peptide. In showing a prompt and significant increase in CNP in tissues driving normal endochondral growth, these findings provide further rationale for CNP agonists in the treatment of growth disorders resistant to current therapies and support the use of CNP concentrations as biomarkers of linear growth.

“…Four types of NP receptors (NPRs), named NPRA, NPRB, NPRC and NPRD, are present from cyclostomes to mammals [for references, see Takei et al (Takei et al, 2011)]. In particular, NPRC-like receptors are expressed in the atrial and ventricular myocardium of the eel (A. anguilla), while the ventricular EE appears to express an NPRA-type receptor that is able to bind ANP and VNP with almost equal affinity (Cerra et al, 1996).…”

“…With the exception of a few species -medaka (Oryzias latipes), which does not possess ANP, and eel (Anguilla japonica), which lacks BNP (Takei et al, 1991;Takei et al, 1994a;Takei et al, 1994b) -all NPs are expressed in teleosts. Recently, BNP was also detected in the rainbow trout (Oncorhynchus mykiss) (Johnson and Olson, 2009).Four types of NP receptors (NPRs), named NPRA, NPRB, NPRC and NPRD, are present from cyclostomes to mammals [for references, see Takei et al (Takei et al, 2011)].

The eel heart: multilevel insights into functional organ plasticity

SummaryThe remarkable functional homogeneity of the heart as an organ requires a well-coordinated myocardial heterogeneity. An example is represented by the selective sensitivity of the different cardiac cells to physical (i.e. shear stress and/or stretch) or chemical stimuli (e.g. catecholamines, angiotensin II, natriuretic peptides, etc.), and the cell-specific synthesis and release of these substances. The biological significance of the cardiac heterogeneity has recently received great attention in attempts to dissect the complexity of the mechanisms that control the cardiac form and function. A useful approach in this regard is to identify natural models of cardiac plasticity. Among fishes, eels (genus Anguilla), for their adaptive and acclimatory abilities, represent a group of animals so far largely used to explore the structural and ultrastructural myoarchitecture organization, as well as the complex molecular networks involved in the modulation of the heart function, such as those converting environmental signals into physiological responses. However, an overview on the existing current knowledge of eel cardiac form and function is not yet available. In this context, this review will illustrate major features of eel cardiac organization and pumping performance. Aspects of autocrine-paracrine modulation and the influence of factors such as body growth, exercise, hypoxia and temperature will highlight the power of the eel heart as an experimental model useful to decipher how the cardiac morpho-functional heterogeneities may support the uniformity of the whole-organ mechanics.Key words: autocrine/paracrine regulation, contractility and relaxation, Frank-Starling response, neuro-humoral modulation, sarcoplasmic reticulum, transduction cascades. all levels of cardiac organization from gross morphology to molecular biology (Katz and Katz, 1989). As illustrated by Olson (Olson, 2006), this results from the modular morphogenesis of the heart driven by distinct transcriptional regulatory programs. Hopefully, this review may also help to illustrate how the fish heart, like all vertebrate hearts, accomplishes a multilevel physiological integration, i.e. homogeneity of function, compensating for its morpho-functional heterogeneity.I also wish to emphasize that, due to their commercial value and laboratory amenability, many eel species are now considered critically endangered, thereby calling for ethical considerations. This would imply a critical decision when choosing this animal as an experimental model for biomedical research. Cardiac morphological designThe eel heart consists of four chambers placed in series: a sinus venosus, a thin-walled atrium, a more muscular ventricle and an outflow tract (bulbus arteriosus) (Fig.1). The peripheral venous blood flows in sequence from the sinus venosus to the atrium, to the ventricle and to the bulbus arteriosus, from where it is pumped to the gills to be oxygenated and then distributed to the body, reflowing to the heart. The sinus venosus is a large chamber separated fr...
